MAX1456CWI+T

Sensor And Detector Interfaces Overview

The MAX1456CWI+T is a low-power, 12-bit analog-to-digital converter (ADC) from the MAX144/MAX145 family. It operates on a single +2.7V to +5.25V supply and features a successive-approximation architecture with an internal track-and-hold circuit. The device provides a maximum sampling rate of 108ksps and consumes only 3.2mW at full speed. It includes an automatic power-down mode reducing current to 0.2µA and a fast wake-up time of 2.5µs. Data is transferred via a high-speed, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

Sensor And Detector Interfaces Feature Summary

• Single-supply operation ranging from +2.7V to +5.25V
• Low power consumption with automatic shutdown capability
• Internal track-and-hold structure for signal acquisition
• High-speed 3-wire serial interface compatible with standard protocols

Sensor And Detector Interfaces Applications

• Battery-powered systems
• Portable data logging
• Medical instruments
• Process-control monitoring

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'CWI' against official manufacturer documentation to confirm package type and temperature range. Ensure the ordering code matches the exact component requirements for your design. Cross-reference with Analog Devices or Maxim Integrated databases for availability and lifecycle status.

Sensor And Detector Interfaces Selection Notes

Select this component when a 12-bit resolution and 108ksps throughput are required in a space-constrained environment. Consider the pseudo-differential input configuration of the MAX145 variant if differential signaling is needed. Evaluate power constraints to utilize the automatic shutdown feature effectively.

Sensor And Detector Interfaces Part Context

This part belongs to the MAX144/MAX145 series of low-power ADCs. The MAX145 variant specifically supports one pseudo-differential channel, distinguishing it from the dual single-ended channel MAX144. Both share the same pinout and core functionality within the 8-pin µMAX/DIP packages.

Sensor And Detector Interfaces Replacement Considerations

For pin-compatible 10-bit alternatives, consult the MAX157 and MAX159 data sheets. Verify electrical characteristics and interface compatibility before substituting with other ADC families.
